l IMPROVEMENT IN LOCOMOTIVE ENGINES.

TO ALL WHOM ITMAY GONCERN: g

. Be it known that we, SAMUEL SAMUELS, of Mott Haven, in the county-ofWestchester, und 'State of New York, and WALTER P. BRASSINGTON, ofBrooklyn, in the county of Kings, and State of New York, have invented acertain new and useful improvement for Supplying Locomotive Tenders withWater, of which the following is a full, clear, and enact description,reference being had to the accompanying drawing, forming part of thisspecification, and which represents u side elevation of a. locomotiveandftender with our improvement npolied thereto, details employed inwhich are partly shown in section.

-The object of our invention is the supplying of locomotive tanks ortenders with water, by means of a. vacuum produced in such tanks,whereby, on the attachment of a hose or pipe establishing o connectionof the same with an outside reservoir, et n considerably-lower level itmay be than the track, the water is, by the natural pressure of theexternal atmosphere, forced into the tank to supply it.

The nature of our invention consists in establishing the vacuum in thetank C, by the mechanical agency of a pump, worked by thelocemotiveengine, an`d' in the arrangement of parts of the feed-pump withreference to the boiler, engine, and tender, whereby to exhaust the airfrom the tank, and in the arrangement of the air pipe relatively to thewater-valve, for exheusmg air from the tank of the tender. These devicesfor supplying locomotive tenders with water essentially differ fromthose pions which employ the direct agency of steam for lthe purpose,whether using the pressure of `the steam on the surface of the water inthe reservoir, or condensing it in the tank to elevate or feed the waterby reusonof n vacuum, though the mechanics-l agency we'employ may, ifdesired, be used in connection with the lutter.

Referring to the accompanying drawing, A represents the feed-pump of undas applied to a. locomotive engine, and the location of which may bevaried. B is the water-supply pipe to said pump, that is provided withvalves a b c, and the supply pipe furnished with a cock, Il, whichlatter is used to shut oif or establish communicution with the tenderlC, or water-took thereof, near its bottom. D is an air pipe connectingthe watersupply pipe B with the upper portion of the tank. Thisconnection I prefer to establish in front of the cock lil, and connector control the cock c by a rod or h nndle, e, from the platform of theengine or its tender. Though capable of various modifications, as, forinstance, in the disposition` of the pump, several pipes and valves, orin the employment of a. separate pump for-exhausting from the tank tothat which is used for pulnping water into the boiler,'the arrangementof parts represented in the accompanying drawing, while possessingadvantages peculiar or incidental to it, but which are not of necessityrequisite, will serve to illustrate the peculiar character or principleof our invention, which distinguishes it from others, and the operationof which is as follows: l

When'itis desired to exhaust the nir from `the tank of the tender C, thecock d is shut und the cock c is opened by means ofthe handle or rod e.This stops the action of the pump as regards its feeding water from thetankand restricts it to exhaustion of nir by the pipe D, which airforced along the Water-supply pipe B, is expelled through the cock cintothe outside atmosphere, say by o. discharge nozzle, f. On the otherha-nd,when. it is desired to stop exhausting air, and confine the pump Ato forcing wot-er from, tbe'tank into the boiler of the engine, the cockc is shut, and the cock d is opened, whenthe vulve b will be broughtinto play, in conjunction with the valve a, to forcethe wat-cr asrequired. Of course the action of" the pump may be stopped or put on atpleasure for either purpose. To cause water to flow from an outsidereservoir or pool by pressure of the external atmosphere into the vacuumin the tank, it will only be necessary to insert the outer end of a.pipe or 4hose attached to e nozgle under control lof a vulve, arrangedat any suitable position in the upper portion of the tank, say at apoint indicated hy red lines in thc drawing. By using the same pump Aforboth exhausting the nir from the tank, und forcing the water into theboiler, there is a simplicity of arrangement as compared to theemployment of separate pumps; nlso'o. similar advantage in connectingthe nir pipe D in front of the cock d, with the supply pipe B, thatserves to supply water to thc pump.

What is here .claimed as new und useful, und sought to be secured byLetters Potent, is-

1. The combination, with the tank of a. locomotive engine tender, of ansii-pump so arranged as to admit of being worked bythe engine, for theproduction of n. vacuum in said tank, substantially as herein serforth.V

pipe'B, infront of the Vsaid co 2. The combination, with a. loco-motiveengine and its tender,.of n. pump so arranged n to serve either purposeat peasure, of 'exhausting air from the tank to facilitate supply of.water to the latter, or nf forcing water lfrom the tank into the boiler,substantially as herein set forth.

3. `In colbination with the Water-supply pipe B, and its stop-cock thenir pipe D connccted'\vith the ck d, essentially as. shown anddescribed. v Y 'SAMUEL SAMUELS,
